Don't generate ternary if contains raises

[JSAbrahams]

Relevant issues

• Resolves #365

Summary

Do a check before generating a ternary if one of the branches does not contain a node which would generate invalid Python output. We verify that both then and else branch don't contain:

• A code block.
• A raise statement.

Added Tests

Happy

• Re-add raise in one line if, verify generate Python if not ternary
• Added handle test to verify separate handle parse rule.
